Tekla ifc to revit, solid.byunion node acts weird

  1. I imported tekla ifc file into revit(green element)
  2. and changed tekla element to revit system wall family element(grey element)
  3. And I got the solids of the revit system walls and used solid.byunion node to make them one solid
  4. But, the surface, which I thought was supposed to be one, is turned out to be Two surfaces like below image.

  5. I thought it was because the two surfaces could not be aligned, so I aligned and it worked like below image

  1. But it’s almost impossible that I do this to every single wall in the project.

  2. I think tekla works different from revit. The walls in tekla acts like separated elements like below image, otherwise acts like one in revit. I think this difference is the key point to solve this problem

  3. And, I just found out that the coordinates(xyz) are different like below. I just don’t understand what happened. The coordinates system works differently between revit and tekla, so after converting to revit element, it just happened…? What if I round up all the coordinates so they has become same coordinates.

Q. Is there a way I import tekla ifc file and solid.byunion node works the way I want(one surface, not two)? Thanks in advance!

Hi @qpqp1065 ,

Maybe you can try to create a surface in Dynamo to merge the two Tekla elements, then you can merge those Dynamo Surface and then create a Solid from that.
